Ancient Tools Revealed by Melting Arctic Ice

Warming temperatures are melting patches of ice that have been in place for thousands of years in the mountains of the Canadian High Arctic and in turn revealing a treasure trove of ancient hunting tools... The results have been extraordinary: Andrews and his team (including members of the indigenous Shutaot'ine or Mountain Dene) have found 2,400-year-old spear throwing tools, a 1000-year-old ground squirrel snare, and bows and arrows dating back 850 years.
